All cells need energy to survive. They obtain this energy by carrying a series of chemical reactions that are collectively known as respiration.
What are the products of aerobic respiration?
Carbon dioxide and water
Water and lactic acid
Ethanol and carbon dioxide
What are the conditions required for anaerobic respiration?
Plenty of oxygen
Lack of oxygen
Plenty of water
What are the reactants for aerobic respiration?
Glucose and carbon dioxide
Glucose and water
Glucose and oxygen
Where does aerobic respiration occur in animal cells?
Cytoplasm and mitochondria
Just the cytoplasm
Just the mitochondria
Which of these is a product of anaerobic respiration in human muscle cells?
